Inventor: GUMADA MASAHARU
IPC: C21D9/46
Filed: 1987-08-20
Granted: 1990-08-13
Abstract: The method involves preparing an alloy sheet having a composition consisting of 30 to 50 wt.% of Ni, 1 to 5 wt.% of Ti and the balance Fe and incidental impurities. The alloy sheet is perforated by etching. The etched alloy sheet is subjected to a solution heat treatment to forming the alloy sheet after the solution heat treatment into a predetermined form. The formed alloy sheet is subjected to an age-hardening treatment by holding the alloy sheet within a non-oxidising atmosphere at a termperature ranging between 650 and 750 deg.C. The alloy sheet after the solution heat treatment is subjected to a surface blackening treatment, thus forming a black film on the surface of the alloy sheet.

Title: Multilayer polymeric film
Inventor: BAIRD JAMES CLARK
IPC: B29C48/08
Filed: 1989-06-23
Granted: 1996-07-26
Abstract: A polymeric multilayer film structure having a high percentage of fillers is disclosed. The fillers are concentrated in a separate filler containing layer having about 5 to about 20 percent of the thickness of the total multilayer film. The filler containing layer is coextruded with a base layer comprising the balance of the thickness of the multilayer film. By keeping the filler containing layer thin, relative to the total film thickness, a multilayer film having a filler concentration up to about 60 weight percent is achievable without significantly adversely affecting the material properties of the multilayer film structure.

Granted: 1992-05-18
Abstract: The system includes a scanner (10) for  reading  letters  and documents and for outputting image data. An optical  section  (30) is formed in accordance with the output image data of the  scanner (10), and the output signals  of  the  optical  section  (30)  are stored in memories (20A)(20B) by distinguishing the reference data of a training step and the input data of the recognizing step. The distinguished data are compared with  each  other  by  a  computer (20), and letters and documents are recognized based on  a  letter recognizing algorithm or a document recognizing algorithm  by  the same computer  (20).  Based  on  the  forms  of  the  letters  and documents inputted from the computer  (20),  the  optical  section (30) converts  the  Fourier-transformed  diffraction  patterns  to electrical signals. Thus a real time processing becomes possible.

Abstract: A security thread (1) for a bank note comprises a discontinuous magnetic thread (3) which has binary coding, the binary values being denoted by the presence or absence of bit lengths of thread. The coding employed is repetitive, comprising alternating termination segments (4) and word segments (5). The length of a termination segment in terms of bit lengths is less than the length of a word but is greater than the maximum length permitted within a word of bits which have the same binary value as the bits in a termination segment. The invention provides resistance to false readings and, by varying the parameters of bit length, word length, length of the termination segment and otherwise, a multiplicity of different codings having the same general format.

Title: Manufacturing process for a cordless telephone keypad
Inventor: KANG DAE-SONG
IPC: H04M1/26
Filed: 1992-06-15
Granted: 1995-01-24
Abstract: LED LAMP The fabricating method of key pads reduces manufacturing cost by using conductive carbon rubber instead of imported carbon ink. The method comprises the steps of: (A) die consisting of inner and outer cylindrical parts (3a,3b) made of silicon rubber; (B) joining the conductive silicon rubber (7) with the bottom of the inner cylinderical part; (C) connecting the inner cylindrical part to the outer cylindrical part via connector (3c) made of silicon rubber by molding; (D) pressing die punch (8) fixed to the die flange (9) by a power press.
